In a press release he stated: "I felt the time has come to seek new opportunities in my life."

"At the same time, I am one hundred per cent committed to doing my best for Nokia until my very last working day. I am also really looking forward to this year's Nokia World and sharing news about exciting new devices and solutions."

Vanjoki has a six month notice period, so there's plenty of time to bring someone else in. But unless that person comes complete with a smartphone from 50 years in the future, it's difficult to see how Nokia is going to offer anything that will turn consumers' heads in the next year or two.
